Sadly, the Steve Spangler Science Club is just a scam.
We anticipated receiving interesting science experiments every month. Instead, we got cheap toys. First it was Magic Sand, which you can buy at Target in the toy aisle. Now this month we got Plus Plus Blocks - no experiment or instructions. We got a toy thrown in a box.
You may think I'm exaggerating but I'm not. Literally what you will receive is a cardboard box with a toy inside it, plus a little brown wrapping paper. That's it.
No wonder they don't give refunds...
